There are two alternatives that were analyzed in the Environmental Assessment:
No-Build Alternative
The No-Build Alternative would retain the existing state route and roadway configuration throughout the SR-66 project area except for those modifications to the roadway network that have been programmed and approved for implementation, as identified in TDOT’s 25-Year Long Range Transportation Policy Plan, State Transportation Improvement Program (STIP), and the TDOT 10-Year Project Plan and would allow for routine maintenance and safety upgrades.
Build Alternative
Improvements consist of widening the existing two-lane roadway along SR-66, from SR-34 to near Speedwell Road/Old Highway 66, from ten-foot travel lanes (existing) to 12-foot travel lanes (proposed), adding paved shoulders four- to ten-feet in width, adding an intermittent 12-foot-wide two-way left-turn lane and two-foot curb and gutter, as well as adding 5-foot sidewalks near the beginning of the proposed project.
